Title: Repair welding of stainless steel
Inventor: OZAKI TOSHINORI
IPC: B23K31/00
Filed: 1978-03-22
Abstract: PURPOSE: To prevent the occurrence of intergranular corrosing and stress corrosion cracks by reducing the time of welding by making rewinding by removing a specific range of heat-influencing portion after welding when a repair welding for a specific thickness of stainless steel is made with a specific beveling depth.  
     CONSTITUTION: An experiment shows that when a stainless steel of a thickness d 1  of 20 mm ≠ d 1  ≠ 90 mm and a conical or a groove-shaped beveling depth d 2  of  d 2  > d 1 /3 with a diameter D 1  and a width D 2  is welded for beveling and then the  place from which the heat-influencing portion around the beveling is removed in a  range smaller than D 1 /3 or D 2 /3 is carefully rewelded, stress corrosion cracks and  intergranular corrosion caused by heating can be provented. The setting of the  beveling depth d 2  to d 2  > d 1 /3 is for lessing problems arising from heating influence. Thus, since prewelding can be performed comparatively roughly, the time of welding can be curtailed. Welding at d 1  < 20 mm is possible without heat influence  but at d 1  < 90 mm the effect is not clear.

Title: Semiconductor breaker
Inventor: TANAKA MINORU
IPC: H03K17/725
Filed: 1984-02-20
Abstract: PURPOSE:To detect an open state and abnormality accurately regardless of a load and without depending upon an open command by incorporating a small- capacity AC power source in the breaker and detecting whether a main circuit is closed for the AC power source or not. CONSTITUTION:When the breaker is on, GTOs 1 and 3 are both turned on under a turn-on command (on gate signal), so almost all of the voltage of an AC power source 8 is applied across a resistor 9 through a resistor 9, diode 2, and GTO3 in the positive half cycle of the voltage of the AC power source 8 or through a diode 4, GTO1, and resistor 9 in the negative half cycle of the AC power source 8. When the breaker is off, the GTRs 1 and 3 are both turned on under a turn-off command and the resistance value of the resistor 9 is much smaller than the leak resistance of the GTRs 1 and 3 and diodes 2 and 4, so almost no voltage is applied across the resistor 9. The output of a voltage detector 10, therefore, depends upon neither the characteristics nor the state of the load and the turn-on and turn-off states of the breaker is judged securely from the output level of the voltage detector 10.

Title: Powder deposition preventing means for electrostatic powder spray gun
Inventor: SHIMIZU KOUICHI
IPC: B05B5/025
Filed: 1979-03-19
Abstract: PURPOSE: To prevent powder coating material from deposition by a method wherein a cylindrical electrode has inner diameter larger than powder passage by a specified dimension and a ring-contacting needle electrode is actuated by compressed gas flow.  
     CONSTITUTION: Cylindrical electrode 2 has internal diameter 1W10mm larger than powder passage 11. To hollow room 9 behind the electrode 2, compressed air is fed through gas inlet 12, and jetted toward the electrode 2 surface through slit type outlet or multi-hole outlets 8a. This produces positive pressure in the concave zone and prevents powder coating material from deposition. To prevent powder from depositing on needle electrode 1, compressed air comes through gas inlet 13 and enters cylinder 5 when coating is started. This extends spring 15 to push valve rod 3, so that gas is continuously jetted through gas outlet 7 and minimizes powder deposition. When coating is stopped, spring 15 forces the needle electrode 1 back to the original position, and deposited powder is scraped off with ring 4.
